Project cannot work.

[Xing-C]

My project encountered a problem today. I have tried to create a new project, but still prompted this error. I don't have a clue now. Can you help me?

gradle.properties :

# Fabric Properties
	# check these on https://modmuss50.me/fabric.html
	minecraft_version=1.20.1
	yarn_mappings=1.20.1+build.10
	loader_version=0.14.22

# Dependencies
# check this on https://modmuss50.me/fabric.html
fabric_version=0.89.0+1.20.1

Output information of IDEA:
